GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(423, 857) = 362511

GCD(423, 857) = ( 423 x 857 ) / 362511

= 423 / 857

= 423

Step2:

LCM(1, 256) = 256

GCD(1, 256) = ( 1 x 256 ) / 256

= 1 / 256

= 1

So, Greatest Common Divisor of 423, 857, 256 is 1
